Predator Grizzly Cable Wiring Standards

Predator Grizzly cables provide a consistent RJ45 based wiring standard for a wide range of RS232 communications. In addition, support for half duplex RS485 communications is included within the Predator Grizzly cable standard. Different Predator adapters convert RJ45 connections to DB9, DB25 or terminal screw style connections.

800+ CNC machines, robots, CMMs, PLCs, 3D printers, markers, presetters and test stand makes and models are supported. Whenever possible standardized colors are used to simplify day to day use. 100+ part numbers are members of the Predator Grizzly cable system. All part numbers honor the following wiring standards for plug in play connections.
